Supplemental Looper review method for duplicated business rules, reuse, responsibility boundaries, unnecessary complexity, abstractions, and test maintainability. Use alongside the base correctness review, not instead of it.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Maintainability review Read this method and [the examples](references/examples.md) before reviewing. Follow the existing Looper prompt's output, publication, scope, and repair-frontier contracts. This method adds no output fields, tool requirements, agents, or publish permissions. ## Boundaries - Keep the full base correctness review. On the first pass, cover all in-scope changes, not just code that looks repetitive or long. - On re-review, check existing findings, new commits, and directly affected code. Do not restart a refactoring audit of unchanged historical code. - The agent's structured findings are the review conclusions; repository rules and PR intent supply their basis. Infrastructure signals do not decide whether a semantic concern is valid. - Prefer reuse, consolidation, or deletion over a new abstraction. Reducing lines or increasing reuse is not a goal by itself. ## Investigation 1. Read PR goals/non-goals, linked requirements, and repository rules. Identify the changed behavior and its intended boundaries. …

How to install
mdr add nexu-io/looper/maintainability-review@sha256:7a8c4771240f2973The line at the top of this page pins the label git:20261028.259a20e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
